What are the thoughts regarding the efficacy of Over The Counter " Octane Boosters"?

Would they offer any performance improvement in a Track Day situation?

If there is any value, what is the best brand to use?

If the thought are that it is hokey, is there any downside to using one - other than wasting $5 - 10?

Thanks.
 
Do a search on "octane MMT Torco toluene" and read more than you ever wanted to know.
 
Bottom line from a practical standpoint: 'WASTE OF TIME & MONEY.

Such a long winded expose!:rofl
 
The only way you'll see a perceived 'performance boost' is if you are using a fuel that's of poorer octane level than your car is tuned to or has a knock sensor that retards timing. In which case all you are doing is bandaiding poor quality fuel. If you add booster to fuel that's already got a decent octane rating for your car, then you're just wasting money.

Ya, well, you know how I am! :lol
 
Thanks

Thanks for the input.

I might try to read up on the tech stuff later, but for now, getting Octane Booster is one less thing I have to do tomorrow.

My take-away is: good gas; good tune; GREAT car; no need!
